cases the seed is found still attached to its pedicel ; both 

 pedicel and cupule are studded with capitate glands 

 (Figs. 143, I44)j usually borne on a stout, multicellular 

 stalk. The cavity of the head is empty, and the whole 

 structure is identical with that of the glands on the leaf

and stem of Lyginodendron, at a stage when the secretory 

 tissue has perished (compare Fig. 145, from the cupule 

 of Lagenostovia Lomaxi, with Fig. 146, from a petiole 

 of Lyginodendron). No other fossil plant is known with 

 glands of this kind, and, considering the close and 

 constant association of the seed with the vegetative 

 organs of Lyginodendron, there can be no doubt as to
